Abstract

PCT No. PCT/FR90/00596 Sec. 371 Date Jul. 3, 1991 Sec. 102(e) Date Jul. 3, 1991 PCT Filed Sep. 7, 1990 PCT Pub. No. WO91/03633 PCT Pub. Date Mar. 21, 1991.A safety device for controlling circulation of a cooling fluid of an engine includes a valve seat, a poppet movable toward and away from the valve seat, and a temperature sensing device including a movable element for controlling the movement of the poppet toward and away from the valve seat. A eutectic solder element connects the poppet to the movable element and melts at a predetermined safety temperature. A first spring engages and urges the movable element and hence the poppet toward an engagement with the valve seat. A second spring engages and urges the poppet away from the valve seat opposite to the first spring. Thus, if the cooling fluid reaches the safety temperature and the solder element melts, the second spring moves the poppet away from the valve seat and allows the cooling fluid through the valve seat. Preferably, the movable element includes an enlarged portion, the valve seat includes a retention member extending therefrom, the first spring is compressed between the retention member and the enlarged portion, and the solder element directly connects the poppet to the enlarged portion. The poppet also preferably includes a central opening in which the enlarged portion and the first spring are partially received and movable through when the solder material melts. Further, the valve seat also includes a second retention member, and the second spring passes about the movable element and is compressed between the enlarged portion and the second retention member.
